Tumor Progression and Homeostasis
1976Publisher Summary The idea that cancer evolves as a series of sequential heritable cellular changes is quite old. It probably had its genesis in the common clinical observation that human neoplasia often appears to undergo change during its clinical course, such that what was originally a relatively benign tumor of low grade is transformed over a ...

Gliomas are the most common primary brain malignancies, with different degrees of aggressiveness, variable prognosis and various heterogeneous histologic sub-regions, i.e., peritumoral edematous/invaded tissue, necrotic core, active and non-enhancing ...

Tumor hypoxia and cancer progression
Cancer Letters, 2006Aerobic life consumes oxygen for efficient production of high energy compounds. The ability to sense and respond to changes in oxygen partial pressure represents a fundamental property to assure the cellular oxygen supply to be within a narrow range that balances the risks of oxidative damage vs. oxygen deficiency.

Chromosomes and Tumor Progression
1980Chromosome studies suggest that most neoplasms are unicellular in origin (i.e., "clones"), and that biological progression, typically associated with loss of "differentiated" properties, results from acquired genetic instability in the neoplastic population leading to sequential appearance of increasingly mutant subpopulations with greater selective ...

Cyclooxygenases, prostanoids, and tumor progression
Cancer and Metastasis Reviews, 2007In response to various growth factors, hormones or cytokines, arachidonic acid can be mobilized from phospholipids pools and converted to bioactive eicosanoids through cyclooxygenase (COX), lipoxygenase (LOX) or P-450 epoxygenase pathway. The COX pathway generates five major prostanoids (prostaglandin D(2), prostaglandin E(2), prostaglandin F(2)alpha ...

Tumor Progression and Catastrophe Theory
1993Progression is the development from bad to worse that is often observed in tumors. It can follow different courses, not only in different organs, but also in the same organ: sometimes there is a smooth, continuous progression from normal to malignant cells, sometimes suddenly a highly malignant tumor arises.

Gene amplification and tumor progression
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 1993Proto-oncogenes are the genes which are most frequently found amplified in human tumor cells. Acquisition of a drug-resistant phenotype by gene amplification is frequent for in-vitro cultured cells but is very rare in human tumors. Proto-oncogenes amplified in human tumors belong essentially to one of three families (erbB, ras, myc) or to the 11q13 ...
